Gum irritation from Canker sores?

Ok, background: a week ago I had a flu like symptoms- fever, body aches, sore throat bla bla bla. Fever went away after 24hrs along with body aches, sore throat did not. Dr said no strep, just a severe sore throat.(started warm salt water 3+ times a day as soon as sore throat presented itself.)
The next day I see/feel a canker sore starting to build, then by the end of the day I see 4. By morning I see multiple on my tongue and inner mouth starting to build up ( I have never had more than one at a time in my lifetime- i'm 41) About the this time, my gums around my teeth ( which I have no issues) start to get real sore, including the roof of my mouth is tender/swollen too. The next morning, I have multiple full blown canker sores, my gums hurt when I brush my teeth so much that it was almost impossible to brush. I am still doing the warm salt water, and have added hydrogen peroxide to my routine. It's been almost a week, some of the canker sores are starting to disapate, some are not, and the gums although better are still sore to brush. A few questions:
- Is it common for the gums and roof of the mouth to get that tender from canker sores?
- why would the gums get inflamed from canker sores that are on the tongue, inner lip, and cheek?
- will to much hydrogen peroxide rinsing cause this gum irritation? ( I know it's a stretch...)
- Once the canker sores are gone, will the gumm irritation go away too?

I appreciate anyone's input, especially if this has happened to you.
And yes, I know I should go to my dentist, but I'm on the road working til Christmas. So if that is your answer, thanks, but I understand that..... thank you all again.
